INKING DEVICE FOR PRlNTlNG-PRESSES.

%PEC5IFICATION forming part of Letters Patent No. 441,789, datedDecember 2, 1890.

Application filed November 1, 1889. Serial No. 328,943. (No model.)

To whom it may concern.-

Be it known that I, JOSEPH L. COX, of Battle Creek, in the State ofMichigan, have invented certain new and useful Improvements in InkingDevices for Printing-Presses; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked IOthereon, which form part of this specification,

in which- Figure 1 is a side elevation of the inking form-rollers of aprinting-press, showing my improved devices for adjusting the form-roll-I 5 ers independently and simultaneously. Fig.

2 is a perspective View of one of the formroller-journal supports, andFig. 3 is a sectional View through the same.

This invention is an improvement in printing-presses wherein a series ofrollers are employed to distribute the ink as it is carried from thefountain to the type; and it consists, essentially, in novel devices forsupporting the form-rollers and rendering them simul- 2 5 taneouslyadjustable, so that they maybe set to properly supply the ink to thetype and when necessary simultaneously set off or throw apart from thedistributing rollers, which supply the ink thereto, to allow foreign 3osubstances-such as paper-which may eas ually work or be caught betweenthe form and distributing-rollers-a common occurrenceto be readilyremoved without disturbing the working adjustments of or removing theform- 3 5 rollers, all of which will be clearly understood from thefollowing description and claims.

The invention is principally designed for use on presses having areciprocating bed for carrying the forms, which is movedback and forthbeneath the form-rollers, and the drawings indicate the invention asapplied to such a press.

Referring by letters to the drawings, \V designates a portion of themain frame of the 5 press, and X designates a portion of thereciprocating fOIIllsupporting bed. On the part IV, which is ahorizontal bar, are secured brackets A, that form partof the devices forsupporting the form-rollers. Each bracket has a horizontal portion a,which is longitudinally slotted, as at a, and on the upper edge of whichis an inwardly-projecting flange a which rests upon the top edge of bar\V, while portion a lies against the face thereof, andis secured theretoby a screw-bolt B, passing through slot 0, and tapped into a suitablethreaded opening in the bar, as indicated in the drawings. By means of aflange a and bolt B the bracket is kept in a horizontal position, and atone end of the bracket is a cy- 6o lindrical offset A, which isvertically bored and elongated, as shown,

C designates a bearer consisting of a body 0, fitted. and resting in thebore of offset A and having a tubular bearing C on its upper end, inwhich is received one journal of a form-roller, and in the lower end ofsaid bearer within the ofiset A is a vertical bore 0, internallythreaded, as indicated in Fig. 3.

Ddesignates a bolt engaging bore 0 and projecting below offset A, asindicated. The bearer and bolt D can be adjusted up and down in the boreof offset A or moved longitudinally therein; but the bearer has nolateral play or oscillation. 7

E designates a longitudinally-movable camrod supported in stirrups orloops to on the bar IV below the brackets A, and upon the upper edge ofsaid rod rests the heads of bolts D, so that by this means the severalbearers 8o 0 are upheld. The upper edge of the bar is notched, asindicated at e e, adjoining each bolt-head, the one side of the notchbeing illclined, as shown, to form a cam-surface, so that as the bar isshifted longitudinally the bolts D may ride easily down into the notchese or up therefrom, as is evident.

It should be understood, of course, that there is another set ofbrackets, bearers, bolts, and a longitudinally-movable can1-rodsupporting the bolts, as shown and described, at the opposite side ofthe machine, this being necessary to support the form-rollers ateaeh endand effect their proper adjustment.

F designates a rock-bar mounted in proper 9 5 supports (not shown) onthe main frame and provided with crank-bar f, which is connected to theend of cam E by a slot and pin G, as shown, and has a handle g, by whichit can be shifted so as to throw rod E back and forth, as desired.

There are, as shown, four form-rollers 11 H,

arranged in two pairs, and each roller H has its journal h engaged inthe tubular bearing 0 of an adjoining bearer C. Above each pair ofform-rollers is a distributing-roller I, which is driven by gearing froma rack 011 the bed, as indicated, if desired. Above and between therollers I I is a roll J, which receives ink from the fountain by anysuitable delivery apparatus, (not shown,) and from which the ink iscarried by composition rollers K K to rollers I I, as indicated. Byturning any bolt D the bearer O, that it supports, can be raised orlowered on bracket A, and of course the corresponding end of the roll Hsupported by the bearer is adjusted accordingly, so that by this meansthe form-rollers can be accurately aligned with the distributing-rollersI on the type-bed. Should any paper or other substance get between theform and distributingrollers, the pressman can by shifting bar. E dropall the bearers, and thus simultaneously separate the form anddistributing rollers without any disturbance of their adjustment, andafter the removal of the foreign matter the form-rollers can be movedback to work ing position together and the press at once started, thusavoiding vexat-ious delays in readjusting the rollers. I

Having thus described my invention, what I claim, and desire to secureby Letters Patent thereon, is

1. The combination of thesleeved brackets attached to the main frame,the bearers 0,

playing vertically in the sleeves of the black-- ets, and a cam-barbelow the brackets, with the bolts D, supported on said cam-bar andhaving a threaded connection With the bearers C, for the purpose andsubstantially as described.

2. The combination of the horizontally-adjustable brackets A A, boltedtothe main frame, the vertically-movable bearers C 0, playing throughsaid brackets, the rollers journaled in said bearers, and the horizontalrods for simultaneously adjusting and supporting said bearers, allsubstantially as specified.

-3. The combination of the horizontally-adjustable brackets A A, thevertically-adjustable bearers C C and the form-rollers supportedthereby, and the cam-bar E for simultaneously raising or lowering saidbearers, substantially as specified.

4. The combination, in a printing-press,of the form and distributingrollers, the horizontally-adj ustable brackets A, theverticallyadjustable bearers G O, supporting the formrollers, theadjusting and supporting bolts D D for said bearers, an dthelongitudinally-movable cam-bars E, sustaining said bolts, all substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.
